There are many security problems with Electronic Commerce since insecure public networks, especially Internet, are used. Therefore, for implementing secure Electronic Commerce, CAPI(Cryptographic Application Programming Interfaces) is expected to use various form of security applications. The Cryptographic Application Programming Interface supports cryptographic services for each level and various security services. The CSSM API(Common Security Service Management Application Programming Interface) Provides modularity, simplicity, and extensibility in terms of various add-in modules and interfaces in contract to other CAPIs. This paper proposed an applying method of CSSM API having various extensibility and supporting multi-platforms to Electronic Commerce. we describe encryption, digital signature operation of CSSM API's CSP interface and evaluate secureness by matching relation of theratening factors to security services.

Recently, it is progressing a study for supporting various application services using OpenAPI(Application Program Interface). But it is not enough a study related OpenAPI(Open Application Interface) to access many collected context data of sensor networks for ubiquitous application services. Therefor, this paper presents Pull/Push service model based on sensor networks, and implements OpenAPI fer Pull/push application services. And, we design and implement OpenAPI using web service for Pull application services. This Pull OpenAPI supports users the context data of temperature and humidity using the remote service based on .Net framework in sensor networks. And, we design and implement OpenAPI using TCP/IP socket interface for Push application services in sensor network. This Push OpenAPI provides users a state of temperature, humidity collecting in sensor networks. Consequently, user can develop easily various application services as supporting OpenAPI instead of closed application interface of sensor networks based on existed specific database.

Domestic construction industry is larger in size, and its shape is more complex. As a result, collaboration and information management tasks are difficult to manage in a way that conventional 2D-based exchange of information. BIM technology was introduced as a solution for this. But BIM only provides a very limited set of features such as Constructability review, clash detection in reality. and duplication of work and a lot of iterations occurs in BIM process. Thus, it takes quite a lot time to work. We studied how to improve the work efficiency by connecting API to business processes. Using the API in the integration process by automating repetitive tasks, reduce a significant amount of work time Using API (Automation, Optimization, Interoperability, Analysis) can solve the task problem that does not solved by the basic features, If we make good use of the combined API will be improved productivity.

In order to vitalize the Rich Communication Service-e(RCS-e) service, RCS-e users need various ways to use RCS including RCS-e apps. A RCS standards organization has suggested Application Program Interface(API). Since it only dealt with functional requirements, it was not enough to implement the API. This paper suggests an open API framework that can utilize RCS-e through a web interface. By using the framework, web developers can implement various RCS-e-enabled web applications. A system architecture is defined for the framework. Call flows for establishing a RCS-e session between the framework and other nodes are defined. Also, rules and examples for translating protocols between them are provided. Finally, performance evaluation proves that the proposed framework does not add loads to the existing network infrastructure.

Google Maps have changed the response time of Web-GIS using AJAX technologies. In addition, Google released the Open API named Google Maps API(Application Programming Interface) and it lead to the big paradigm on the Open API, where the SDK(Software Development Kit) and ASP(Application Service Provider) had ruled at the related map market. In short, the Open API has been paradigm-shifting for the web mapping. After this, government, many companies and open source foundations have guided Web-GIS market's growth through releasing the relevant Open APIs. So many comparative analysis on web-mapping API carried out by many researches. However there were no researches that can be applied to our current domestic environments. This paper investigates components of web-mapping API. Then we compare how many components supported and enumerate features for each of those APIs. Finally this paper presents direction of future development of Web Mapping API.

This paper aims to establish an efficient national R&D Application Programming Interface (API) management system for national R&D data-driven management and explore the possibility of using operational data according to the recent global data openness and sharing policy. In accordance with the trend of opening and sharing of national R&D data, we plan to improve management efficiency by analyzing operational data of the national R&D API service. For this purpose, we standardized the parameters for the national R&D APIs that were distributed separately by integrating the individual APIs to build a national R&D API management system. The results of this study revealed that the service call traffic of the national R&D API has shown 554.5% growth in the year as compared to the year 2015 when the measurement started. In addition, this paper also evaluations the possibility of using operational data through data preparation, analysis, and prediction based on service operations management data in the actual operation of national R&D integrated API management system.

In Windows operating system, CSPs(Cryptographic Service Providers) are provided for offering a easy and convenient way of using an various cryptographic algorithms to applications. The applications selectively communicate with various CSPs through a set of functions known as the Crypto API(Cryptographic Application Program Interface). During this process, a secure method, accessing data using a handle, is used in order to prevent analysis of the passing parameters to function between CryptoAPI and CSPs. In this paper, our experiment which is using a novel memory traceback method proves that still there is a vulnerability of private key and secret key disclosure in spite of the secure method above-mentioned.
